f To all whom it may concern: Be it known that I, ALEXANDER GREELEY, of'Stephensville, in the county of Outagamie and State of Wisconsin, haveinvented a new and useful Improvement in Saw-Sets, of which "thefollowing is a specification: The object of this invention is to furnishan apparatus for setting the teeth of saws which shall be more usefulthan the saw-sets heretollfore made and it consists in the constructionI and arrangement of parts hereinafter de- 5 scribed. Inthe accompanyingdrawing, Figure 1 represents a side view of the saw-set, partly in 1section 5 and Fig. 2 is a vertical section of Fig. r 1 taken on the linea: w. r f Similar letters of reference indicate corre- .sponding parts.

A is the bed-piece, having upon its under side a shank, B, by which thesaw-set is attached to a bench or table. 0 is a plate upon which the sawis laid, made adjustable on and secured to the bed by the screw D. E isa vertical column, attached at its lower end A, to the.bed, which ismortised out above the p bed. F is the jaw, which is made to operatedirectly on the saw-teeth. G is the clamp-bar for clampingthe saw-plate.H is a screw which works in the top of the column E, by which theclamp-bar is forced down as the end of the screw bears upon the top ofthe bar when the screw is turned down, as seen in the drawing. I is aloose rodzwhich passes through the center of the screw and through theclamp-bar, with its end resting on the top of the jaw F. J is acam-lever pivoted on the top of the screw. When the lever is raised therod I is forced down by-the cam, and operates on the jaw I 7, The backmotion of the jaw is produced by the spring K. The forward end of thisspring is UNITED STATES PATENT OFFICE.

divided, so that a part passes up on each side of the jaw, with theirends bearing against the under side of the clamp-bar,.and holding thatbar up from the plate 0 when the saw is withdrawn. means or thethumb-screw m for governing the position of the saw on the plate 0. N isa thumb-screw for adjusting the jaw I and O is a'screw for adjusting theclamp-bar G. By means of these screws the jaw and the clampbar areadjusted to saws of different thickness, so that the action of the camwill be uniform at all times.

When a saw is placed upon the plate (J the --clamp-bar is forced down tothe saw-plate by gage L, and the plate 0 may be so adjusted that thepoint only of the tooth will receive the jaw. The saw-set is thereforeadapted to very fine as well as coarse toothed saws. The teeth of thesaw are set or bent by raising the cam-lever and forcing down the jaw F,as before stated.

. Having thus described my invention,I claim as new and desire to secureby Letters Patent- 1. A saw set, composed of the bed A, column E, jaw F,clamp-bar Gr, adjustable plate 0, rod I, screw H, and cam-lever J,arranged to operate substantially as described.

2. In combination with the jaw F and clampba-r G, the adjusting-screws Nand 0, substantially as described.

3. The spring K, combined with the jaws F G, as and for the purposedescribed.
